DENDROLOGY

Detailed explanation-1: -Vascular plants are efficient in growth and development due to the presence of vascular tissues: xylem and phloem. Xylem is responsible for the transport of water and nutrients from the roots to the rest of the plant. Phloem carries the sugars made in the leaves to the parts of the plant where they are needed.

Detailed explanation-2: -Nonvascular plants do not possess any special organs for the absorption and transport of water; instead, the plant cells absorb water and nutrients from their wet surroundings at their surface by diffusion and pass them from cell to cell.

Detailed explanation-3: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
